A retrospective clinical study was carried out to evaluate the efficacy of homoeopathic treatment in a series of asthmatic patients. Twenty-six patients suffering from bronchial asthma with at least one year's follow-up were included in the study. Treatment outcome for cure was at least one year free of any asthmatic symptom with a general improvement in health and removal of mental, general and local symptoms and ailments not incurable, while treatment outcome for improvement was improvement of their health but without complete cure of mental, general and local symptoms, bronchial asthma symptoms being less intense and less frequent but present or with a remission of less than one year's duration. Twenty-two remedies were used including Sulphur (19 patients), Calcarea carbonica (14 patients), Lycopodium clavatum (12 patients) and Pulsatilla (10 patients). The effectiveness of the homoeopathic treatment was confirmed (57% cured, 23 % improved), however factors such as duration of illness, suppression due to conventional drugs and family history complicated and prolonged treatment and as a result made some cases incurable.
